Solved: Re: i have two questions on your

ruimartins1000 · ‎08-01-2017

Hi,

based on the new 8.5, I'm trying to deploy a vWLC on AWS.

So, I've downloaded the vWLC OVA from Cisco site. I want a new deployment, so this is the only thing I have.

I understand we need to create a EC2 instance, but not from the "normal" procedure on AWS Console, 'cause it will ask for a disk deployment.

How can I attach the OVA to a EC2 instance?

On the config guide they say:

Step 1	Go to AWS and from under Management Tools, select CloudFormation.
Step 2	From the Select Template page, use the Upload option to upload the vWLC template

which Template is this one? I've tried the OVA but it returns an error saying it is too big.

Also, I believe it is expecting a JSON File with the instance caracteristics to be created. But then, I don't understand how to map the OVA....

Any hints please?

Cisco vWLC config Guide 8.5

UPDATE: I've tried to make a VM Import with the vWLC OVA on AWS Bucket but it has failed with error message:

"Client Error: No valid partitions. Not a valid volume."

Thanks, Rui

I'm also looking forward to the mentioned CloudFormation template.

Attached you'll find a vPC Template but you need the authorization for AMI which is not yet public

ruimartins1000 · ‎08-09-2017

Thanks;

I've used the template and pointed it to my AMI. the Cloud Formation completed without errors and the EC2 instance has been created.

But it crashes exactly the same way as before.

So, my conclusions are that the template is only helping on creating the interfaces and Elastic IP and attaching it to the correct interfaces. And points to the AMI which has to be built.

I conclude that my issue is with the AMI I've created. Actually there's no description from Cisco from where to start to create the Snapshot. I've described my procedure previously, but somewhere I'm making a mistake.

AWS Snapshot origin supported formats are: "The following disk formats are supported: Virtual Hard Disk (VHD), ESX Virtual Machine Disk (VMDK), and raw." There's no reference to QCOW2 and that format fails as expected.

Update:

I'm at a point where the EC2 instance I've created crashed on Boot saying it cannot map the Eth1 to dtl0.

I've made these steps:

I've deployed vWLC 8.5 OVA on VMWare, made the post-install adding the IP Addresses that will map into AWS Subnets.
Shutdown the VM and Export it as OVF. -> Got the VMDK.
Import the VMDK to AWS as snapshot using CLI (aws ec2 import-snapshot)
Created an AMI from this Snapshot
Launch a EC2 instance based on the AMI
it crashes...

I've created all the AWS infrastrcuture: VPC, Subnets, IGW and Security Group.

Any hints?! thx

ali aqrabawi · ‎08-17-2017

i have two questions on your steps :

Shutdown the VM and Export it as OVF. -> Got the VMDK

>>> when i export OVF from my vspher i get two OVF , from which shall i expor the VMDK ?

2. Created an AMI from this Snapshot

>>>shall i use the default setting when i create the image from the snapshot ? or i need to change something ?

ruimartins1000 · ‎08-22-2017

Hi!

1 - I got these 3 files after exporting from vSphere. I used File -> Export -> Export OVF Template

Export Files

2 - Yes. It took me some while to figure it out that only HVM Virtualization is supported.

When you are at EC2 Snapshot -> Create Image -> Choose HVM as the Virtualization Type

Image Virtualization Type

The Paravirtual (default) option, keep crashing the instance at boot with several kernel nasty errors.

Let me know how it went. 'cause I'm still not successful on this deployment. I'm at the same point I've described. Thanks

ali aqrabawi · ‎08-23-2017

i had same issue as yours , but i managed to move step forward ,

follow this link and it will pass that eth1 error :

https://thewebfellas.com/blog/creating-an-new-ec2-ami-from-within-vmware-or-from-vmdk-files

let me know if you need any help .

still unable to login to the wlc

ruimartins1000 · ‎08-24-2017

Hi Ali,

Still no success. Followed the link and used the AMI Tools from CLI.

Build the AMI, launch it and got into the same error:

XML config selected
Validating XML Configuration
!!!!! could not get mac address from network interface
(...)
fail to add eth1 to dtl0

this a complex setup...

ali aqrabawi · ‎08-24-2017

did you launched the instance using cloudformation ? if not , please try

damolp · ‎10-20-2017

Managed to get it working with both the ec2-ami-tools and VM Import/Export. I can give access to the AMI if needed.

Crash due to missing eth1 below. Maybe Cisco can fix this so it doesn't crash and instead warns the user ;)

Hi damolp,

Great news! Can you share what was the trick to create an AMI that don't crash please?

By the way, have you see the latest 8.5 version and documentation? Cisco completely eliminates vWLC for AWS from their documentation... not on RN, nor on Deployment Guide....

Hi ruimartins1000,

I've same error today with Hyper-v, it was all down to not having two network adapters in the virtual machine setting. (eth0, eth1) in IOS

Added another adapter and the vWLC boot fine.

I guess you need to added another adapter in AMI if available and then it should boot.

Hope that help.
